What does Chapter 7 say about Sai Baba's attitude towards caste and ritual purity?

Chapter 7 of the Shri Sai Satcharitra explains that Sai Baba completely transcended caste distinctions and conventional ideas of purity. It is stated that caste did not matter to him in the slightest, and he was the same to all, whether they were Shudra or from another caste. The text highlights that even the 'best of Brahmins' and keepers of the sacred fire (Agnihotris), who were typically very proud of their ritual purity, would prostrate before him. Furthermore, it's mentioned that he had no ego regarding the body and felt no disgust even if a dog were to put its mouth in the food being served, demonstrating a profound detachment from worldly norms.
